Found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela. In Suriname found on the forest floor in the far south interior.

Habitat

Prefers tropical owland evergreen forest, terra firme.

Reproduction

“The nest was an unlined, loosely interwoven mat of dry, slightly curved leaf rachises placed flatly in an enlarged chamber at the end of a burrow. The nest measured 12.5 cm
across, with the shallow nest cup interior 5 cm in width and 1.75 cm in height. The straight, undeviating burrow was 50 cm in length with an entrance tunnel 5 cm high and 13 cm wide. The burrow was horizontally excavated in the vertical wall of a depression. The depression measured 1.05 m deep and .97 m wide and was 1.5 m from the trail. Distance from the burrow opening to level ground at the top of the depression was 20 cm.” (quote Denton and Blue-smith, ORNITOLOGIA NEOTROPICAL 11: 173?175, 2000).

Clutch size is 2 eggs, nestlings are fed by both parents. No further data.

Feeding habits

Diet consists of invertebrates, caught by leaf tossing on ground mostly alone or sometimes in pairs.. Forages by hipping (not walking) on ground and exposing prey using its bill to flake and toss ground material like rotten logs and leaf litter. Also ants and during brooding fruit is fed to the chicks..

Conservation

This species has a large range, with an estimated global extent of occurrence of 5,500,000 km2. The global population size has not been quantified, but it is believed to be large as the species is described as ‘frequent’ in at least parts of its range (Stotz et al. 1996). Global population trends have not been quantified, but the species is not believed to approach the thresholds for the population decline criterion of the IUCN Red List (i.e., declining more than 30% in ten years or three generations). For these reasons, the species is evaluated as Least Concern.
Black-tailed Leaftosser status Least Concern

Migration

Sedentary throughout range.
